Hemoperfusion in diabetic coma.
Hemoperfusion on ionic exchange resins in the therapy of diabetic keto-acidosis (DKA) coma is proposed. Resins used are strong anionic resins in mixed form able to release bicarbonates and to trap ketoanions and organic anions in a stoichiometric manner. A series of trials in open circuit are performed in order to search for a suitable mixture of resins and to establish the amounts of HCO3- and ketoanions respectively released or entrapped. Therefore, ten simulated hemoperfusions in closed circuit systems were performed, utilizing cartridges containing 1,700 g of mixed resin (9% HCO3- form and 91% Cl- form). The results indicate that all side effects of bicarbonate i.v. therapy of DKA coma are avoided because of the smooth HCO3- administration to the patient. Furthermore, a good removal of ketoanions and organic acids is obtained without changing the blood osmolality.
